Short answer
Simply stretching a small image makes it blocky. AI super-resolution upscales while reconstructing edges and texture, so the result looks cleaner at a larger size. Unblurry offers on-device super-resolution and up to 4x upscaling, with a before/after slider so you can judge the real result. Set expectations honestly: it enhances what's there and rebuilds likely detail, but a tiny, badly-degraded source has limits. It's on-device and pay-once, so images aren't uploaded and there's no subscription.
Try Unblurry on a real example first, and check the current App Store listing for exact features and pricing before you decide.

Quick comparison
| Need | What to check | Why it matters |
|---|---|---|
| Pricing model | Check whether useful features require a subscription, a one-time unlock, or neither. | The cheapest app on day one may not be cheapest after a year. |
| Privacy model | Prefer on-device work when the content is sensitive. | Private documents, resumes, study data, and family content deserve careful handling. |
| Export / lock-in | Confirm file formats, sharing, backup, and deletion controls. | A good app should help you finish the task, not trap your work. |
